I've been a long time Android user, but around a year ago I became fed up. The interface was updated to be more "intuitive", and in turn it became like a glue-eating-child version of iOS. Android's navigational structure was appealing to it's users, and in trying to become more like iOS, they ended up getting rid of what their users loved and failing to deliver what iOS users loved
For example, I used to be able to search for "Mobile Hotspot", and it would just show me the mobile hotspot settings page. Last I checked, searching for it brings up help articles and a bunch of stuff, and the actual mobile hotspot setting page isn't there. Why would you show me a help article for the thing I'm trying to do instead of just showing me the thing I'm trying to do?
I'm willing to wager their interface was a result of "consenses through meetings" between management, marketing, and UX / UI designers. No individual could be absurd enough to make such bad decisions. They desperately need someone to spearhead their interface design with someone that understands their core users accept that these users do not use iOS for a reason, and focus on a UI that maximizes the experience they enjoy.
Beyond the interface were the irritating bugs. If my Samsung phone lost service, it wouldn't just retry looking for a signal. I'd have to go into airplane mode then back out to force it to search for a signal. This was beyond irritating. Android auto would constantly disconnected from my car, except for when I wanted it to. If you ever made the mistake of enabling the driving mode on your phone, getting out of it was absurd. Try restarting your phone, your car, or burning both in a dumpster, and your phone would still stay stuck in driving mode with this irritating interface. The phone would just become absurdly slow over time with terrible battery degradation. Calling over Wi-Fi would constantly fail to actually use Wi-Fi. I get bugs are a thing, but these are core things that any reasonable QA department should catch.
There's also the issues with random things just breaking. Any tech person with a family full of Android users can probably tell you about constantly having to fix random things on their parents phone's which defy any explanation for why it's broken. My family are no iPhone users.
Then there's security. The Play store is basically just a malware distribution center.
And the camera, oh the camera. The zoom was insane, and on a hardware level should outperform an iPhone. However, for whatever reason, I found that the pictures taken on my friend's iPhones were always better than my S21 or S22. Someone needs to invest into the digital processing of images on Androids. AI based enhancement would be a great place to start, but not sure if anyone is actually steering the ship there and they're just leading by managerial consensus / making decisions to avoid doing what's wrong (and thus rarely doing what's right).
I'm an iPhone user now. I still dislike iPhones, but not as much as I hate what Android has become. I want to use a Samsung device again and would gladly fork over money if they can stop making terrible choices and implement some reasonable QA.
